Hi,

Context: 

Model: G30 
Several years back, I adeptly upgraded the 5AT (Driving Assistant Plus) system, necessitating a replacement of the steering wheel. It got retroffited sucsefully. Yet, some months later, I stumbled upon an ISTA error:

S 0693 - No communication possible with: Electric steering lock 
ELV ECU showed red on ecu trees.

The car was working fine, so I ignored it. 

Issue:

A few days ago, I flashed all the ECUs with the latest Psdzdata Full 4.46.11 and...

The recurring issue flagged by ISTA remains consistent: 'Electric Steering Lock.' However, this time, the car fails to initiate startup. Upon pressing the start/stop button, a red warning illuminates on the dashboard, indicating 'Steering lock.' Battery is fully loaded with external charger.

So, I think somehow code has changed and don't allow the car to startup with the "No communication possible with: Electric steering lock" fault. I am trying to flash with an old PSdZData-Full, but difficult to get it. Shipment: 17-03-519.

Any other help? Thank you very much

1. Steering wheel SHOULD have nothing to do with ELV.
2. So remains unclear WHY you started to get that message. Have you disconnected ELV? ELV is only present on manual transmission G30s. Is you car manual or have you broken BDC coding or WTF did you do???
3. Forget about downgrading firmware... IF that is the only fault you currently have, issue is with BDC and you CAN'T downgrade it. So SOLVE the problem.

1. Correct, ELV should't appear as ECU because the car is automatic.
2. I got this suddenly after flashing. Firstly, I flashed just BDC with no issues at all; I was even driving. The next day, I wanted to flash DKOMBI, but unfortunately, all the ECUs were accidentally marked, and it flashed all the ECUs... My mistake
3. But with flashed BDC there were no problem.

I never understood why ELV was there. Two days of testing things, and nothing resurrected the car

Have you flashed with VCM update enabled???

Because my logic...
1. ELV is in ISTA because 99% you broke SVT stored in the car (and added ELV in there).
2. IF you JUST broke SVT I doubt it would cause no start condition.
3. The simplest common denominator is you have mangled FA to be manual car or something like that. Then flashing with VCM enabled rewrote SVT to contain ELV and coding BDC now made it also expect ELV...

OR there could be alternative reason that 4.46.1x is NOT supporting your car yet. ISTA has execution break, but you clearly used ESys, so NO break...

---

P.S. That still makes sense ONLY if you now have MORE FAULTS regarding coms, NOT only S0693.

P.P.S. Given you flashed not with ISTA: HAVE YOU reset starter lock after flashing!!!??? NOT doing that will prevent car from starting IF BDC was flashed.

---

P.P.P.S. So IF you have more faults - post them ALL here, because your story still makes little sense.

No. I disabled "Update VCM after Tal Execution".

1. So, Could I fix it?
2. Yes, it would be strange because this fault was always there.
3. Didn't make lot of changes in FA and I had the factory FA and comparing with it, it seems good.

Correct, I used eSys. Never code with ISTA+.

I am going to test Vehicle again with ista+ to check more faults.

Ive reset "starter lock" several times but no luck.

I will be back with new vehicle test faults.

Again, little sense... If you have VCM update disabled so even if you break FA, SVT in car stays the same... So question whether you had VCM update enabled BACK THEN when you did retrofit.

1. Fix is not hard, get proper FA, enable VCM update and do some any coding or flashing.
2. You said it appeared after you did retrofit, so logical conclusion that you had VCM update enabled back then and you used BROKEN FA.
3. List ALL the changes you did. ESPECIALLY if you changed type code!

ALIVE!!!

FIXED FA > TAL calculation > Flashed DME > Code Some ECUs and ELV disappeared = start up sucesfull

No more ELV at eSys.However, checked faults on ISTA and still there th F* S0963 and red ecu in tree. (removed faults and test and still there)

Car working all correct after a good driving test.

Thank you for helping! After many tries I did it.

If the FA is truly fixed code some module with vcm update enabled -> should remove the red ecu and fault.

Sounds like you also have wrong FA written to a car - fix it.

I have revised it but don't find anything strange in it.

Will do. Thank you!
